Senators push Treasury to give states a real seat in GENIUS…

A bipartisan group of senators led by Republican Cynthia Lummis — chair of the Senate Banking Committee's crypto subcommittee — has written to Treasury Secretary Scott Bessent demanding explicit procedural guidance for states seeking to certify their stablecoin oversight regimes under the GENIUS Act. The letter, also signed by Democrats including Angela Alsobrooks, Catherine Cortez Masto, and Kirsten Gillibrand, argues that Treasury's April proposals failed to spell out timelines or certification requirements, leaving state regulators effectively sidelined.

Why it matters

The GENIUS Act — the Guiding and Establishing National Innovation for U.S. Stablecoins Act — does allow for state-level stablecoin supervision, but only where states can demonstrate their frameworks are substantially equivalent to the federal standard. Without a clear certification pathway, the senators warn, the process "could be interpreted or applied in a manner that effectively forecloses future participation" by state regulators. That ambiguity matters enormously: dozens of states are already drafting their own GENIUS-aligned rules, and a federal process that ignores them risks fragmenting the U.S. stablecoin regulatory landscape before it even takes shape.

Market impact

For stablecoin issuers, a dual federal-state oversight structure — if properly implemented — broadens the pool of compliant operating environments and could accelerate institutional adoption. The senators are now pressing Treasury to publish written procedural guidance with clear timelines and flexibility for varied state legislative calendars. Resolution here would remove a meaningful regulatory overhang for the stablecoin sector and reinforce the GENIUS Act's role as the definitive U.S.
